Cosmic Mongoose
I'm moving this here to avoid derailing another thread with OTU foo.
I pointed out that the OTU backstory explicitly includes it. It does. That you think it is absurd is not the point.
Edit: Fair enough. I really should know better when it comes to canonistas and anticanonista studies. Grognards, I swear.
On the same page, is the exact method used by the ancients-massively accelerating a smaller mass into collision- resulting in a small belt,[edit -wrong] with most of the mass scattered.
Not antimatter.
Edit: I'm removing a snarky bit, and adding the note that I did misstate the result as being a belt. Thanks to Vile for pointing it out. It still suggests that there are ways to hammer a planet using the technology described-but obviously not to leave a result indistinguishable from a natural asteroid belt.
Which, possibly, was why they were tagged as anomolous. I don;t know, short of detailed description of why they were identified.
As to why planetbusting was used.....I'm not even touching that. I never liked the whole grandfather thing. Its just one theory, or possibly a coverup, IMTU.
EDG said:That said, and to possibly throw a wrench in, if your TU is OTU based, its always been surmised that the ancients final war is responsible for some asteroid belts -particulalry the anomolous ones. Which gives you a bit of a cover-all ....*
The Ancients would need enough energy to not only blow apart the planet but to also have each fragment going faster than the escape velocity of whatever is left behind. And then magically spread that material around the star as a belt, before it manages to re-coalesce as a planet through the gravitational attraction of all the bits. All of which is ridiculous overkill, considering that the aim of destroying a planet is to just wipe out whatever is there (heck, just wiping out whatever is there can be done much more efficiently and with less ridiculous energies by other means).
captainjack23 said:Thus my caveat. Like it or not, in an OTU close campaign its an issue. Your critiquing the OTU (again) isn't really what was asked for, or relevant.
You raised it as a previously mentioned possibility, and I'm pointing out how it's a ridiculous one. If you didn't want it discussed, you shouldn't have raised it yourself.

[/quote]EDG said:According to the calculations here (in section 6), it would take about 25 trillion tons of antimatter to destroy an earth-size planet so thoroughly that it doesn't reassemble itself after being exploded (i.e. it forms an asteroid belt around the star).

Pulverized by impact with blunt instrument
You will need: a big heavy rock, something with a bit of a swing to it... perhaps Mars.
Method: Essentially, anything can be destroyed if you hit it hard enough. ANYTHING. The concept is simple: find a really, really big asteroid or planet, accelerate it up to some dazzling speed, and smash it into Earth, preferably head-on but whatever you can manage. The result: an absolutely spectacular collision, resulting hopefully in Earth (and, most likely, our "cue ball" too) being pulverized out of existence - smashed into any number of large pieces which if the collision is hard enough should have enough energy to overcome their mutual gravity and drift away forever, never to coagulate back into a planet again.
A brief analysis of the size of the object required can be found here. Falling at the minimal impact velocity of 11 kilometres per second and assuming zero energy loss to heat and other energy forms, the cue ball would have to have roughly 60% of the mass of the Earth. Mars, the next planet out, "weighs" in at about 11% of Earth's mass, while Venus, the next planet in and also the nearest to Earth, has about 81%. Assuming that we would fire our cue ball into Earth at much greater than 11km/s (I'm thinking more like 50km/s), either of these would make great possibilities.
Obviously a smaller rock would do the job, you just need to fire it faster. Taking mass dilation into account, a 5,000,000,000,000-tonne asteroid at 90% of light speed would do just as well. See the Guide to moving Earth for useful information on manoeuvring big hunks of rock across interplanetary distances. For smaller chunks, there are more options - a Bussard Ramjet (scoop up interstellar hydrogen at the front and fire it out the back as propellant) is one of the most technically feasible as of right now. Of course, a run-up would be needed...
Earth's final resting place: a variety of roughly Moon-sized chunks of rock, scattered haphazardly across the greater Solar System.
Feasibility rating: 7/10. Pretty plausible.
